BRUSH.

Bpeoioation of Lettera Patent.

Patented Nov. 19, 1912.

Application led September 7, 1809. Serial No. 516,583.

To all whom it may concern:

Be it known that I WILLIAMCUTHBERT- soN a citizen of the nited States, residing at hicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Brushes, of which the followin is a specification.

My invention relates to brushes, and has for its object to provide a new and useful form of liquid-carrying, sanitary brush.

The invention is illustrated in one form in the accompanying drawing, wherein- Fi re 1 is a plan elevation and part sectiona view of the brush; Fi 2, a sectional view with the parts in a di erent position.

Like parte are indicated by the same letter in a the figures.

A is the handle cylinder having at one end a screw-threaded removable cap A1 and a screw-threaded removable ca A1, and at the other, the screw-threaded p ug A.

B is a Eiston rod having the longitudinal channel 1 therethrough, and the chamber B1 with ball valve B' and seating s ring B* in the upper end. The outer en of the chamber is partially closed by the screwthreaded ring C. On the outside of the piston rod is secured, by a screw thread or otherwise, the piston D, upon which seats the inwardly-opening cup valve D1 within which and about the lpiston rod lies the washer D, adjustably eld in position by the nut D'. Projecting from the plug is the screw-threaded portion E, ada ted to be received into the screw-threads recess E1 on the brush body E1, which is in turn screw-threaded onto the piston rod.

F is a shell of some suitable material, such as vulcanized rubber, which surrounds the brush body, and which holds the bristles F1, which form the brush proper.

G is a brush c linder adapted to inclose and be frictional y held upon the shell F, and provided with a perforated-diaphragm G1 and a screw cover G1, which with the perforated diaphragm forms a chamber to receive, for example, an antiseptic powder G1.

H indicates the pumpin chamber between the screw 'plug A an the piston D, such chamber bein formed when the parts are in the position indicated in Fig. 1.

I wish my drawin to be taken-m a sense as diagrammatic, a though they are intended to represent a practical form of the -pumping chamber,

device which I have actually made and used, but, of course, the size, proportions, sha e and relation of the several parts cou d be greatly altered without de arting from the spirit of my invention, an in my claims I shall point out what appears to me to be its essential elements.

The use and operation of my invention are as follows: The device is normally when not in use in the condition indicated in Fig. 1. All the plugs and caps and covers are in position, the brush is inclosed within the rush cylinder, and the brush body is screwthreaded to the plug Iprojection. An air or is thus left. The screw cap is now removed, and the upper part of the cylinder A filled with liquid soap, and the cap again screwed into position. The brush is now ready for use. By unscrewing the brush body from the end of the plug the parts may be brought into the position shown in Fi 2, the piston rod and piston being pulle down, the latter into substantial contact with the upper, inner surface of the plug. The air in the chamber H by this action vis forced outwardly around the edges of the cup valve. All this v1time the ball valve Bu is held in position by the spring B. By now pushing the brush body toward the handle cylinder, pressure will be ap lied to the liquid in the andle cylinder su cient to unseat the valve B and force a quantit of liquid soap down throu h the channel 1 toward the bristles, and t e brush, bein thus su plied with liquid soap in the mi st of the ristles, will be ready for use.- This action may be repeated as often as necessary, for every time the brush body is pushed in the chamber H is opened and filled with air,I which rushes into it along the clearance space between the piston rod and the plug, and every time the brush body is pu led away from the handle cylinder this charge of air is forced into the handle cylinder past the edge of the cup valve.

When the use of the brush is finished, the bristles may be washed in the usual manner, and whatever soap remains in the channel B1 will remain there because of the atmospheric pressure on the outer end of that channel. For convenient transportation the bristles may then be inclosed by the brush cylinder. The antiseptic therein lo ton rod.

2. In a brush the combination with a hollow cylindrical handle adapted to contain a liquid, of a piston, cup valve and piston rod having a duct therethrough,- an air l chamber, with a valve closing said duct,

and means for operating said piston rpd.

3. A brush com rising a liquid containing handle, a bristle iolding member a piston rod mounted upon said bristle hol in member having a duct therethrough and s idably mounted within said handle and a piston and cup valve within said handle connected with and operated by the bristle holding member by means of said iston rod upon which it is mounted to orce the liquid through the 'handle from the duct through the bristles.

4. A brush com rising a liquid containing handle, a bristle olding member, a piston rod having a duct therethrough. attached to 'the bristle yholding member and slidably passing throu h the end of the handle, and a `piston -'on t e end of the rod within and in slidable engagement with the walls of the handle.y

5. A brush com rising a liquid containing h'andle, a bristle olding member, a piston rod having a duct Ftherethrough attached tothe lbristle holding member and slidabl gassing through the end of the handle, sai

uct enlar d at its upper end yto form a valve 'chain r, and a valve and valve seat in 'said chamber.

6. A brush 'comprising a Aliquid containing handle, a bristle oldingimember, a piston rod Ahaving a duct therethrough attached to the bristle holding member and 'slidnbly passing through they end of the handle, a piston on the end of the rod within said aiidle, the 'duct enlar ed at its up er end to form a valve cham er, and a va ve and valve -seat in saidI chamber.

7 A brush comprising a liquid containing handle, a bristle holding member movable with reference to 'each other, a piston rod having a duct therethrou h connecting the interior of the handle wit the bristles and means for forcing liquid therethrough from the handle to the bristles, lsaid means op- 'erable by the relative'movement ofthe parts, 'andcontaining a iston in slidable contact with the walls oft e handle.

8. A brush comprisin a liquid containing handle'and a bristle ho ding member I'movable with reference to each other, a piston rod having a duct therethrou h connecting the interior of the handle wit the bristles and means for forcing liquid therethrough from the handle to the bristles, said means operable by the relative movement of the parts and comprising a piston and valve.

9. A brush comprising a hollow handle, a bristle holding member and a iston and valve connected with the briste holding member and placed in the handle so as divide the same into soap and air rece tacles.

I10. A brush comprising a hollow andle, a bristle holdin member and a iston and valve connecte with the brist e holding member and placed in the handle so as to divide the same into soap and air recepta cles, the air rece tacle intermediate the soap receptacle and t e bristle holding member.
